Phylogenetic tree constructed using the Neighbor-Joining algorithm to evaluate the distance between partial sodA gene sequences of 82 clinical Enterococcus cecorum poultry-origin strains and E. cecorum reference strain (ATCC 43198). The bootstrap values (1000 replicates) are reported as percentage greater than 60 %. The evolutionary distances were computed using the Kimura 2-parameter method and are in the units of the number of base substitutions per site. Evolutionary analyses were conducted in MEGA6
